I'm managing and optimizing global data center connectivity at NCR Atleos for more than 15 enterprise clients each month, maintaining 100% SLA compliance across high-stakes B2B workstreams.

I engineer secure network solutions with BGP, OSPF, MPLS, S2S IPsec VPN, and DMVPN, sustaining 99.9% tunnel uptime. As the Connectivity SME, I configure Fortinet and Palo Alto firewalls, enforce security policies and TLS compliance, and reduced connectivity setup time by 10% through standardized documentation.

Previously at NCR Voyix and NCR, I supported Walmart POS and self-checkout environments, resolving escalated software and network issues across 500+ locations. I maintained a 98% CSAT score, handled 30+ L2 tickets daily, and helped onboard new agents through coaching and knowledge-base updates.

I'm motivated to keep expanding my network engineering expertise and contribute to a large-scale enterprise network environment.
